Non-JSON response on some RPC methods when the request returns an error (same as #7006)

[Denis-score]

Same as ticket #7006 after update to version 2.40.0 who should fix this, we still have invalid json response from certains call like :

Call :

{
	"jsonrpc":"2.0",
	"method":"debug_traceTransaction",
	"params":[
		"0x58f35cae80d0d50fc6fb8a6ffd3ae2a6e1180366cabe0772a5bd91d7466ff686", { "tracer": "callTracer"}
	],
	"id":"1"
}

Response :

{
    "jsonrpc": "2.0",
    "id": "1",
    "result":nullnull,
    "error": {
        "code": -32000,
        "message": "EOF"
    }
}

Hi @jcchevalier-ledger, this issue should now be solved by #7104. I'm going to close this issue down, but feel free to re-open if the problem persists when this finds its way into a release.
